safeTy warnIngs WARNING: Riding an electric motorbike can be a hazardous activity. Certain conditions may cause the equipment to fail without fault of the manufacturer. Like other electric products, the Dirt Rocket can and is intended to move, and it is therefore possible to lose control, fall off and/or get into dangerous situations that no amount of care, instruction or expertise can eliminate.
BefOre yOu BegIn Remove contents from box. Remove the foam separators that protect the components from damage during shipping. Inspect the contents of the box for scratches in the paint, dents or kinked cables that may have occurred during shipping. Because the Dirt Rocket is 95 percent assembled and packed at the factory, there should not be any problems, even if the box has a few scars or dents. MAKE SURE POWER SWITCH IS TURNED “OFF” BEFORE CONDUCTING ANY MAINTENANCE PROCEDURES.
